Domain And Range Of A Function Problems

In the quadratic function y x 2 5x 6 we can plug any real value for x.

Domain and range of a function problems. Given a graph and or verbal description of a situation both continuous and discrete the student will identify mathematical domains and ranges and determine reasonable domain and range values for the given situations. College algebra questions on finding the domain and range of functions with answers are presented. Determine the domain of a function according to the algebraic limitations of that function. The solutions are at the bottom of the page.

Especially in real world problems the domain is restricted even if there is no variable in a denominator or under an even root sign. Put any number into the sin function in your calculator. The domain of y sin x is all values of x since there are no restrictions on the values for x. Domain and range of functions.

Here is a set of practice problems to accompany the functions section of the review chapter of the notes for paul dawkins calculus i course at lamar university. Therefore the domain of the given quadratic function is all real values. This domain is all real numbers greater than 0 or left 0 infty right. Given the graph of a function determine its domain or range.

Thus the domain of the function is left 2 3 right also the variation in the function output is in the continuous interval from 1 to 4. College algebra questions with answers sample 5. Y x 2 5x 6. If you re seeing this message it means we re having trouble loading external resources on our website.

Domain and range problems for a function. We observe that the graph corresponds to a continuous set of input values from 2 to 3. Because y is defined for all real values of x. 22 find the domain and range of the given function.
